Polar Mohr 76em - Error 68

Can anybody please tell me what the error code 68 on my Polar 76em means? It only gives this error when the clamp plate switch under the console is not made. When powered up with the clamp plate in "dead" place under the console and the switch covered, the machine runs fine. The clamp plate switch, as well as all three backgauge switches are in working order. All inputs like their associated LED's on the control board.
Thanks in advance for your help.

 

Hi alleno

Error --68-- means (In program no."0" the measurement for a special size false clamp has been stored, either being smaller than 1.8 cm or larger than 35 cm.)

Turn off machine. Put to rest special false clamp plate on switch S6. Attach service jumper to card IAR.Turn on machine.Erase complete memory storage by using key (program erasing) and key (erase) insert correct size of special false clamp plate into program no. "0" of memory bank.Furthermore please check the fuse F8 and check the battery on board MB.

Hi alleno!
Hi Simon Yeoung!

The selection of the program zero is o. k. and perfect explaned.
I would do the rest bit different. Nobody is using a special false clamp size!
In the latest information it is described different.

If the nominal display shows the error 68 switch the cutter off. Put the false clamp onto its deposit. Switch the cutter on again and
1. In case a false clamp with special width is used, the width of the false clamp plus 10 mm must be entered.
2. When using the standard false clamp actuate the push button “delete” (DEL).

If this does not work let us know. Because the last machines have a little relay in the keyboard. Then we need the machine number (??61???).

Hello, I have the same problem with my Polar 76 EM firmware V4.0. What is the service jumper I would have to connect in board IAR?
Or what should I do to get to the program 0.
Thank you very much.
